| 3 | Stabilization of a high-order harmonic generation seeded extreme ultraviolet free electron laser by time-synchronization control with electro-optic sampling显示文摘A fully coherent free electron laser(FEL) seeded with a higher-order harmonic(HH) pulse from high-order harmonic generation(HHG) is successfully operated for a sufficiently prolonged time in pilot user experiments by using a timing drift feedback. For HHG-seeded FELs, the seeding laser pulses have to be synchronized with electron bunches. Despite seeded FELs being non-chaotic light sources in principle, external laser-seeded FELs are often unstable in practice because of a timing jitter and a drift between the seeding laser pulses and the accelerated electron bunches. Accordingly,we constructed a relative arrival-timing monitor based on non-invasive electro-optic sampling(EOS). The EOS monitor made uninterrupted shot-to-shot monitoring possible even during the seeded FEL operation. The EOS system was then used for arrival-timing feedback with an adjustability of 100 fs for continual operation of the HHG-seeded FEL. Using the EOS-based beam drift controlling system, the HHG-seeded FEL was operated over half a day with an effective hit rate of 20%–30%. The output pulse energy was 20 μJ at the 61.2 nm wavelength. Towards seeded FELs in the water window region, we investigated our upgrade plan to seed high-power FELs with HH photon energy of 30–100 e V and lase at shorter wavelengths of up to 2 nm through high-gain harmonic generation(HGHG) at the energy-upgraded SPring-8Compact SASE Source(SCSS) accelerator. We studied a benefit as well as the feasibility of the next HHG-seeded FEL machine with single-stage HGHG with tunability of a lasing wavelength. | H.Tomizawa T.Sato K.Ogawa K.Togawa T.Tanaka T.Hara M.Yabashi H.Tanaka T.Ishikawa T.Togashi S.Matsubara Y.Okayasu T.Watanabe E.J.Takahashi K.Midorikawa M.Aoyama K.Yamakawa S.Owada A.Iwasaki K.Yamanouchi | 2015 | High Power Laser Science and Engineering2015，3，2： | 1 |

| 6 | Small-diameter vertical shafts constructed in the shallow space of steep mountainous areas显示文摘Japan is a mountainous country comprising several islands,in which mountains occupy 70%of the entire land.Therefore,numerous transmission line towers have been constructed in the shallow space of steep mountainous areas.In such construction,monorails and/or cableways are generally used to transport materials and equipment to the construction site instead of using a construction road,as the former method is more economically viable.However,with this method,drill rigs or vertical shaft sinking machines cannot be transported to the site.Four small-diameter vertical shafts of 2.5 or 3.0 m as the foundation for high-voltage transmission line towers in mountainous areas are traditionally constructed manually in Japan.Over the past two decades,however,dangerous and poor environmental conditions for workers regarding the manual construction of these small-diameter vertical shafts have become a major problem.Meanwhile,owing to the poor environmental conditions of small-diameter vertical shafts to be constructed in the shallow space of steep mountainous areas,a decrease has occurred in the number of young workers entering these projects.Namely,the construction of transmission line towers with using the manually traditional small-diameter vertical shafts is becoming difficult in Japan from abovementioned problems.Hence development of a new technology to solve the problems is necessary for Japan’s economic growth.With this knowledge,the authors have developed a new small-diameter vertical shaft construction system,in which workers do not have to enter the vertical shaft during construction,as machines are used instead.The applicability of the proposed system was confirmed by means of the construction of three actual vertical shafts at two construction sites,as well as in factory and field tests.The applicability and details of the final proposed system are summarized in this paper. | T.Hara A.Yashima K.Sawada K.Kariya H.Tsuji N.Soga | 2019 | Underground Space2019，4，3： | 0 |
| 7 | Role of the first mitosis in the remodeling of the parental genomes in mouse embryos显示文摘Although male and female pronuclei reside in the same zygotic cytoplasm, they differ in many respects, such asvolume and transcriptional activity. The aim of this study is to investigate whether these differences are lost during thefirst mitosis. For this purpose, a new method was developed to inhibit the mixing of two parental chromosomes duringmitosis, thus to induce the formation of two nuclei after they exit from the mitotic phase. In this method, one-cellembryos are arrested at metaphase by treatment with nocodazole, and whn exitting from the mitotic phase, two nucleiwere formed in a single karyocyte following treatment with 6-dimethylaminopurine (6-DMAP). These embryos weredesignated as post-mitotic embryos (PM-embryos), in which the two nuclei were derived from the male and femalegenomes. We found that in the control one-cell embryos that had not been treated with the reagents, the volume of themale pronucleus was about 1.65-fold greater than that of the female pronucleus, whereas the volumes of the two nucleiin the PM-embryos were similar (volume ratio of 1.01). Although a two-fold difference in transcriptional activity wasdetected between the male and female pronuclei in the control embryos, no difference in transcriptional activity wasdetected between the two nuclei of PM-embryos. The ratio of transcriptional activity in the nucleus derived from thepaternal genome to that from the maternal genome was 1.02, for which no significant difference was detected by the χ2fitness test. Therefore, the volumes and transcriptional activities of the male and female nuclei were approximately equalin PM-embryos, which suggests that the asymmetries of pronuclear volume and transcriptional activity between maleand female genomes are somehow losted during the first mitosis. | Kentaro T.HARA Fugaku AOKI | 2005 | Cell Research2005，15，2： | 0 |
| 8 | Microstructure of Nitrided Aluminum Alloys Using an Electron-Beam-Excited-Plasma (EBEP)显示文摘Nitriding of surface of aluminum alloys was carried out with using an electron-beam-excited-plasma (EBEP) technique. The EBEP is sustained by electron impact ionization with energetic electron beam. Two kinds of substrates, aluminum alloys AA5052 and AA5083, were exposed to the down flow of EBEP source at 843 K for 45min. The specimens were characterized with respect to following properties: crystallographic structure (XRD), morphology (SEM) and the cross sectional microstructures of the nitrided layer was observed using a scanning electron microscopy (SEM). There are some A12O3 particles on the surface of the nitrided AA5052 and AA5083. The A1N layers were formed on the substrates with the thickness of 4.5 fi m for AA5052 and 0.5 /z m for AA5083 . A relatively uniform nitrided surface layer composed of A1N can be observed on the AA5052 substrate. The grains size near the interfaces between the substrate and A1N layer were smaller than that near the surface. On the surface of A1N layer, the concentration of nitrogen was high and in the middle of A1N layer it had a constant concentration like the aluminum and the concentration was decreased with approaching to the interface. On the surface of nitrided AA5083, a uniform A1N layer was not formed as the reason for the high nitriding temperature. | L.Liu A.Yamamoto T.Hishida H.Shoyama T.Hara H.Tsubakino | 2004 | 材料热处理学报2004，25，5： | 0 |
